PIA-C-44378 T4 Certified Fabric

This fabric is the real deal. Actual FAA certified reserve parachute material, uncoated 1.1 oz calendared ripstop nylon PIA-C-44378 T4 only made in the United States of America. The very same fabric that is packed into the reserve container of every single skydiving and BASE jumping parachute system.

It may be thin, but with a minimum tensile strength of 50 lbs per square inch, you can rest comfortably knowing these hammocks have you held safe and sound. The uncoated nature of the fabric keeps the hammock from feeling clammy against your skin, and the windproof requirement of true parachute fabric keeps the cold wind at bay.

Button Links

As easy as buttoning your pants, our Button Link system provides a lighter weight and much smaller packing alternative to a traditional metal carabiner.

The Button Links feature 1500 lb Spectra cord, a custom-designed button, and extremely simple assembly. The result is a hammock that has no bulky, heavy metal parts. Button Links can be compressed and packed small into the hammock, allowing us to have a hammock that is lighter and more compact than anything else available on the market.

Spectra Cord

Stronger than steel and far lighter, Spectra is the ideal cordage for our Tree Straps and Button Links. This amazing material is one of the many things that allow us to have extremely lightweight products as well as maintain a very small pack size.

Additionally, we attach our end loops to the gathered end of the hammock using a larks head knot. This knot transfers the stress of hanging to the fabric rather than the stitching on the end of the hammock, resulting in a more reliable, longer-lasting hammock system.

Lock Stitching

All of our products are lock-stitched (stitch type 301) using mil-spec bonded nylon thread. We double stitch our seams at 7-11 stitches per inch following FAA parachute rigging standards. Any more than that (or an additional line of stitching) risks perforation of the fabric which may result in fabric failure.

Lock stitching, as opposed to chain stitching seen on many other hammocks, produces a stronger stitch that is much less likely to unravel and can continue to perform well even if part of the seam has been compromised.

Dye Sublimation

Silk screening, sewn-on patches, and branded fabric tags all increase the weight and pack size of the hammock unnecessarily. We don't think you should have to carry around extra weight for the sake of our branding.

Dye sublimation is the fabric printing equivalency of a tattoo. This process relies on a special ink that, when combined with heat and pressure, turns directly from a solid into a gas. As this gas contacts nylon or polyester fabric, it permanently dyes the fabric resulting in bright, full-color graphics. This system allows us to print graphics and information on our bags without adding any weight or bulk.

I’m a bigger guy at 6’2” 290 lbs and I was a bit scared at first rolling into this thing it held up like a champ. Will definitely be in my backpack for most summer hiking trips. Still amazed at how light it is for how large and it’s weight capacity it has. 5/5

perfect gift

I will not use this hammock but the person who will was VERY HAPPY with the gift. He is an Eagle Scout and knows the outdoors well, this hammock was the one he chose and for good reason. Thank you!

Double Hammock, Ultrawide Ultralight

Super happy with my double so far. Replaced my other backpacking hammock of the same weight, but now I can stretch out and get a diagonal lay in.
There is attention to detail to make this as efficiently light as possible without the sacrifice of strength. Really impressed by the quality of stitching and overall construction.
